My opinion is based on nothing more than conjecture since I am in a non med state. But it seems plenty of people around here have found life long keepers out of a number of strains. A keeper is a keeper and I know plenty of keepers of modern strains are around. But hell what do I know. I haven't been growing for 20 years so that mean I don't know shit right? You want to think the holy grail of ganja should be in every pack of 10 seeds you get, go ahead. Most of us know better.
